In Electrical and Computer Engineering (ECE) curricula, students typically interact with real hardware to gain hands-on experience in dedicated in-person laboratory sections. Remote laboratories are an alternative by allowing students to interact with the real hardware remotely. However, they are often constrained by the cost and space of physical equipment. This paper presents the development of a novel educational remote laboratory for Programmable Logic Controllers (PLCs) that will integrate real hardware with interactive 3D digital twins. Part of Project REDTAIL, this work details the design and implementation of a unified architecture that synchronizes an Arduino Opta PLC with a simulation of a water bottling plant. Our methodology involved instructor interviews to define requirements, followed by the parallel development of the hardware interface, the backend framework, and the 3D simulation. The primary outcome is a functional prototype that validates the technical feasibility of this hybrid approach. By augmenting a single, physical PLC with diverse virtual scenarios, the system directly addresses the scalability limitations of traditional PLC remote laboratories.
